ECON 357 builds upon the foundation developed in an introductory course. Through the use of graphical analysis and mathematical problem solving, we extend the discussion and application of important microeconomic concepts. This course focuses on the decisions of individual consumers, firms, market structures, and the economic rationale of government intervention. Particular attention is paid to the theories of supply/demand, consumer behavior, production and cost, competitive and non-competitive markets, and input markets.

Your final grade in this course will be based on four quizzes, three written assignments, a midterm examination, and a final examination. You must achieve an overall course grade of at least a “D” (50 percent) and a grade of at least 50 percent on the final examination. If your grade on the final examination is below 50 percent, you will not receive credit for the course, even in your overall course grade exceeds “D” (50 percent). The weighting of the composite mark is as follows:

Quizzes (4 @5% each) Assignment 1 Assignment 2 Midterm Final Exam Total
20% 12.5% 12.5% 25% 30% 100%
